Anode material and battery using the same

An anode material capable of improving cycle characteristics, and a battery using the anode material. A disk-shaped cathode contained in a package can and a disk-shaped anode contained in a package cup are laminated with a separator in between. The anode comprises an alloy or a compound including Fe in addition to at least either Sn or Si. The ratio of Fe in the alloy or the compound is preferably 15% by mass or less. Moreover, it is preferable that the alloy or the compound further includes Cr at a ratio of less than 1500 ppm by mass.
